Patch, Patch System And Method For Using A Patch

Abstract

A patch, comprising: a backing disposing thereon an adhesive layer having an adhesive surface for being adhered to a skin surface; and a peelable sheet detachably adhered to the adhesive surface for preserving the adhesive surface and providing a supporting force for the backing. The peelable sheet includes an inner peelable sheet and an outer peelable sheet.

         7 . The patch according to  claim 5 , wherein the inner peelable sheet has an inner edge shorter than either side of that of the first patch area to protect the adhesive surface of the backing. 
     
     
         8 . The patch according to  claim 5 , wherein the region has a geometric shape. 
     
     
         9 . The patch according to  claim 5 , wherein the region is a hole having a geometric shape. 
     
     
         10 . The patch according to  claim 1 , wherein:
 the inner peelable sheet and the outer peelable sheet are respectively provided with at least one inner auxiliary tearing part and at least one outer auxiliary tearing part, in which the outer auxiliary tearing part is protrusive or recessive; and   the inner peelable sheet forms a full circle or a non-full circle.   
     
     
         11 . The patch according to  claim 3 , wherein the third cutting line is a curve, a polyline or a straight line. 
     
     
         12 . A patch system, comprising:
 a physiological parameter detection device having a base patch for being adhered to a skin surface via the base patch;   a backing, disposing thereon an adhesive layer having an adhesive surface, wherein the backing is adhered to the skin surface via the adhesive surface; and   a peelable sheet detachably adhered to the adhesive surface, for preserving the adhesive surface and providing a supporting force for the backing, and including an inner peelable sheet and an outer peelable sheet, wherein the both sheets are relatively easily peelable off from the adhesive surface,   wherein after the inner peelable sheet is peeled off, the outer peelable sheet continuously provides the supporting force for the backing.   
     
     
         13 . The patch system according to  claim 12 , wherein the inner peelable sheet and the outer peelable sheet include at least one inner peelable sub-sheet and at least one outer peelable sub-sheet, respectively. 
     
     
         14 . The patch system according to  claim 13 , wherein:
 the inner peelable sheet and the outer peelable sheet include a plurality of inner peelable sub-sheets and a plurality of outer peelable sub-sheets, respectively; and   a first cutting line is disposed between the inner peelable sheet and the outer peelable sheet, at least one second cutting line is optionally disposed between the inner peelable sub-sheets, and at least one third cutting line is optionally disposed between the outer peelable sub-sheets.   
     
     
         15 . The patch system according to  claim 12 , wherein the backing has:
 a region;   a first patch area; and   a second patch area, in which the first and the second patch areas are extended from the surrounding of the region, and correspond to the inner peelable sheet and the outer peelable sheet respectively.   
     
     
         16 . The patch system according to  claim 15 , wherein:
